Challenge Task 3 of 3 Now we're using a database from a smartphone. It has a phone_book table. It has the columns id, first_name, last_name and phone.
Delete all contacts with the first name of Jonathan and last name of Luna,.

I'll guess that you might not have used two complete comparison expressions in your WHILE clause, or you may not have combined them with the AND keyword.
If I didn't manage to guess the issue, show your query code to make it possible to answer more accurately.

231,236 PointsFor future questions, please always start a fresh new question instead of adding a question onto an existing one.
But your query has two issues:
- the table name in the task instructions is not "contacts " but "phone_book"
- when joining conditions in a
WHEREclause, instead of a comma use the word AND
